Sorry for forgetting to answer the most important Q: "Jordan K. Hubbard" <jkh@time.cdrom.com> wrote: >Any ideas on what I should try here to further debug this oddness? tcpdump on the network on the other end of G's ISDN line (I assume this is the hub/freefall/ampere net) and see if you see the packets from rocky, and if you see ICMP errors from G2 (which I assume is hub), and if your router to the outside world (which I assume is gate-free.cdrom.com) is configured to drop them (bad idea). I assume the PMTU to G2 is at least 1500 and the ISDN link has the narrowest MTU on the path? Bill (Note that when talking about network problems, it's usually best to give real names instead of A and G so that other people can do debugging without having to guess what machines you're talking about)
